Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 332,205,247, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 332,205,247 | |
| -1 | -332,205,247 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 332,205,247.
Example:
1 x 332,205,247 = 332,205,247
and
-1 x -332,205,247 = 332,205,247
Notice both answers equal 332,205,247
With that explanation out of the way, let's continue. Next, we take the number 332,205,247 and divide it by 2:
332,205,247 ÷ 2 = 166,102,623.5
If the quotient is a whole number, then 2 and 166,102,623.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 332,205,247 | |
| -1 | -332,205,247 |
Now, we try dividing 332,205,247 by 3:
332,205,247 ÷ 3 = 110,735,082.3333
If the quotient is a whole number, then 3 and 110,735,082.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 332,205,247 | |
| -1 | -332,205,247 |
Let's try dividing by 4:
332,205,247 ÷ 4 = 83,051,311.75
If the quotient is a whole number, then 4 and 83,051,311.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 332,205,247 | |
| -1 | 332,205,247 |
If you did it right, you will end up with this table:
| 1 | 11 | 41 | 163 | 451 | 1,793 | 4,519 | 6,683 | 49,709 | 73,513 | 185,279 | 736,597 | 2,038,069 | 8,102,567 | 30,200,477 | 332,205,247 |
| -1 | -11 | -41 | -163 | -451 | -1,793 | -4,519 | -6,683 | -49,709 | -73,513 | -185,279 | -736,597 | -2,038,069 | -8,102,567 | -30,200,477 | -332,205,247 |
